Heathrow Airport has approximately 3,200 state-of-the-art Flight Information Displays (FIDS) installed across its four terminals as of 2025, following a recent modernization project.

From LinkedIn and Richard Freeman — I’m really excited to see the impact our new Flight Information Displays are making.

What might appear to be a simple screen replacement is actually the result of years of behind-the-scenes work. We’ve completely re-engineered our content distribution system to be flexible and device-agnostic, enabling us the freedom to thoroughly evaluate the market and select a solution that meets all our requirements.

The new displays from Sharp NEC Display Solutions Europe GmbH, paired with Raspberry Pi compute modules, offer a reliable, secure solution that has a significantly lower hardware cost and are 30–40% more energy efficient than our previous hardware — a major step forward in reducing our carbon and costs.

There’s still many displays yet to be replaced, but I’m thrilled with the initial results.

Thanks to Simon Hayes, Patrick Groothuizen, Alex Bailey and Simon Burgess for their ongoing support throughout this journey

FIDS Installations at Heathrow

Heathrow Airport completed a major upgrade to its Flight Information Display System (FIDS), resulting in about 3,200 display screens throughout all terminals. This modernization aimed to improve operational efficiency and the passenger experience, including enhanced viewing angles and reduced screen glare.adbsafegate

Historical Context

Previous counts and deployments suggested Heathrow once had over 11,000 FIDS screens, but that figure likely involved older systems and multiple auxiliary displays per airline and service point. A more recent source confirms the current number of advanced, networked screens is 3,200 as of 2025.nononsensedesign+1

• Each terminal, airline, and checkpoint features multiple FIDS screens for departures, arrivals, and gate information.nononsensedesign+1

Heathrow’s commitment to efficient information delivery is reflected in the extensive deployment and recent modernization of its Flight Information Displays.
